They kind of swtiched things up and made her want to quit being catwoman and just settle down. Unlike the comics, she wasn't catwoman for the thrill of it. She was catwoman because that's all she had at the time. "Once you've done what you had, they'll never let you do what you want to."

That does make sense. I noticed Nolan's Catwoman was more of a survivor than a thrill-rider. I'll have to give the film another viewing to appreciate that. I'll say though that I disagree she was anywhere near broken like Bruce was, as has already been pointed out he had a setup devoted to how the events of TDK transformed him into a recluse, that is the very height of broken.
